Referring specifically to the drawings, 10 designates the usual casing as employed in connection with oil wells. ,A iiow pipe or discharge tube is arranged centrally of the casing as at 11. Surrounding the 110W, tube or pipe adjacent the top of the casing and ixed so that the tube may slide therein, is an inlet head 12 for power fluid. Power fluid 80 from any suitable source and under appropriate control is applied to the space 13 at the top of the casing and is adapted to enter the head 12 through ports 14 in each of which is preferably fastened a filter 15 such as a piece of textile or metallic cloth, held in place by wing nuts 16. A portion of the bore of the head 12 is enlarged as at 17 to accommodate the power fluid. Suchv power uid may be compressed air, steam or the like.

Surrounding the How pipe 11 vis a power fluid conlining pipe generally-designated 18, the same having an upper section 19 screw threaded to the head 12, a section 2O secured to section 19 by a screw coupling 21,a section 22 secured, by a screw coupling 23 to the section 20, the latter being screw threaded to an upper barrel head 24. Barrel head 24 is held againstsliding movement and has a nipple or pipe 25 rising therefrom and con- 100 stituting part of the low pipel of the well. The lower portion of the ilow pipe 11 is telescoped over the nipple or pipe 25 to form valve means since the telescoped portions as best shown in Figures 3 and 11 have openings 26 therethrough adapted at times to register through sliding movement of the How pipe and normally to remain out of register. When such ports are in register, the power iuid is permitted to return into the How pipe 11 and outside of the Well, to aid in dislodging any obstruction in the flow pipe and generally clean out the entire flow l-ine above such openings. Mounted on the exterior of the pipe 18 in `any suitable manner, are one or more rubber or other swabs 27, of any conventional form, which serve to seal the well against passage of power fluid past the same and thus form the bottom of the chamber 13.

All of the pipes constituting the section 18 are of greater diameter than the flow pipe and hence a passage is provided about the same generally designated 28, for the downward passage of the power fluid.

Disposed in the space 28 are inlet pipes for the power fluid designated 29, the same being screw 'threaded as best shown in Figure 4 to the upper barrel head 24 and the same being perforated as at 30 so that the power fluid mayyenter the same.

Screwed to the barrel head 24 is a barrel section 32 which is also screwed to an upper block 33. Block 33 has another barrel section 34 screwed thereto to which is screwed, at 35, a lower barrel section 36. The lower I barrel section 36 has a perforated oil inlet trap or pipe 37 suitably attached thereto which carries a cage 38 at its top, which is of hollow form, and confines a ball valve 39 adapted to engage a seat 40 therein, at times, this structure constituting the lower or inlet valve of the device for the oil to trap it after it is sucked up, so that it may be pumped or expressed through the iow tube and passages in 'communication therewith or forming part thereof.v f

Fastened in the barrel section 34 as by means of screws 41 is a lower head 42 and located within such section 34 midway of the heads 33 and 42, is a valve mounting block 43 which is rigidly connected with said blocks 33 and 42 by means of short pipes 44,con nected by screw threads to the respective parts as best shown in Figure 15.

A suitable piston is employed within the device having a hollow rod 45 which is slidably mounted through the block-33, pipe44, block 43, pipe 45 and block 42.

As shown in Figure 4, the piston tube or.

rod 45 carries a head 46 of any desired .construction which will provide intimate wiping and sealing contact with the bore of the barrel section 32.' Such piston 46 mounts a cage 47 of skeleton or perforated formas shown which adapted communicate with' the bore oftliebarrel section 32 and Whichfmounts alballfvalve 48 which at times engages a seat 49 carried by the cage. When the va1ve'48'is closed as shown in Figure 4,

`oil in the flow pipe cannot pass the same and return to thewell. On the other hand, ,upward displacement or flow of the oil will? displace the valve 48 f so that the same may pass through the cage and into the flow pipe.

At the lower end of the piston rod 45 and Within the barrel section 36, is a lower piston head 50 which is `of any suitable or conventional construction adapted to intimately Wipe and have sealing engagement with the bore of the section 36.

It will be realized that on the up-stroke Iof the piston, the valve 48 will be closed and to said head 24 and which'are screw threaded in passageways 530i the block 33, such passages converging and communicating with an inlet pipe 54 screw threaded to block 33 and having suitable detachable connection at 55 with the valve mounting block 43.4

Such pipe 54 communicates witha passage 56 in said valve mounting block, said passage being of U-shape, as shown in Figure 25, and has a suitable relief valve 57, mounted in branch 56a of saidpassage 56, said valve 57 being normally closed. Said valve 57 automatically operating to release excessive pressure and power Huid in the event of an over feed into the apparatus.

A valve to control the inlet and exhaust of the power fluid is shown at 58, being of the aoY l through pipes 52 which are screw threaded rotary type and operable on a horizontal axis l and in a chamber 59, with which the passageway 56 communicates through a branch 60. Power Huid entering chamber 59 by branch 60, the valve being in the position shown in full lines in Figure 23, is directed through branch 60l into a passageway 67 to a pipe 67 and from thence through passageway 68 into barrel sectionL 32 under piston 46, thus raising said piston 46, tubular piston rod 45 and the piston 50 in barrel section 36.

During this operation power fluid will be exhausted from the barrel section 36 through a passageway 64 in block 42, a pipe 63 communicating therewith, and a passageway 62 in valve block 43, through a branch 61 into valve chamber 59, then through a branch A 61 into a passageway 66, in the valve block 43, into the space between valve block 43 and block 33, thence into and through passages in block 33, and thence through pipes- 69 screwed or otherwise attached to the block 33 and which communicates with the iow line at ports in the head 24.

Referring to Figure 23, the position of valve 58, as shown in full lines, is such that power fluid is supplied to barrel section 32 and exhausted from barrel section 36 by reason'of the path just traced. When the valve 58 is in the dotted line position of Figure 23 power uid entering valve chamber 59 is directed through branch 61, passage 62, pipe 63 and passage 64 into barrel section 36 above the piston 50, to drive it downwardly, and at the same time exhaust from barrel section 32 takes place through passagev 68, pipe 67, passage 56, through valve chamber 59 and out through branch 61a as above described. A suitable means is provided to automatically shift the position of the valve 58 for the inlet and exhaust of the power fluid. through the operation of the piston, as will now be described. j

Said valve 58 is held in its chamber by a retaining plate 71 screwed at 72 to the block 43, the valve having trunnions 73 and 74, the former being journaled in the block 43 and the latter j-ournaled in the plate 71 and extending outwardly beyond the same and having a pinion 75 fixed thereon. A valve actuatingvslide `7 6 is movable longitudinally of the block43, having an enlargement 77 disposed in a slot or passageway 78 in the block and of such length as to engage .the same at its ends at its' opposite extremes of movement, thus limiting the movement of the valve actuating slide and accordingly `of the valve.

When the valve 58 is in full line position, as shown in Figure 23, the valve actuating slide is held against movement by detent fingers 79 as shown in Figure 5, such `fingers being pivoted at 80 to the block l43 and engaging in notches 81 of the valve actuating slide. After the fingers 79 release the valve actuating slide and the same moves to its other extreme of movement, it is engaged by detent fingers 82 pivoted to block 43 at 83 and engageable in notches V84 of the valve actuating slide.

'Leaf springs-85 are fastened tothe ends of the block 43 and engage the fingers 79 and 82 and urge them into engagement with theirv respective notches.

actuating rods 86 and 87, are employed to spread or release the detent fingers 79 and 82, respectively, from the valve actuating slide 7 6. Such rods are slidably mounted in blocks 42 and 33, respectively, a stufling box 88 preferably being provided in the block 42 about the rod 86: The valve actuating slide has inwardly extending guide members 89 i and 90, through which the rods 86 and 87 pass and coilfsprings 91 and 92 surround and 94 thereon, respectively, and also engaging the projections or abutments 89 and 90. The lingers 79 have inwardly extending projections 95 terminating relatively close to each other and the ngers 82 have similar projections 96. The free ends of the rods 86 and 87 are arranged for abutment respectively, by the piston heads 50 and 46. The springs 91 and 92 are under tension, one at a' time. Thus with the valve in the exhaust position as in Figures 4 and '5, the spring 91 is under tension as a result of the previous movement of the valve actuating slide 76, and

is so held by the fingers 79. The upward movement of the piston head 50-will engage the rod 86, forcing the upper pointed end 91 will cause slide 76 to nuovel to'its uppermost or other position, so that through the intermeshing ofclutch teeth 97 thereon with the pinion 75, the valve 58 will move to vertical position, during which movement the detent 82 will snap into the notches 84 and hold the valve in that position until the descent of piston 46, the same on descent engaging the rod 87, which movement first compresses spring 92, then spreads the projections 96 and disengages the detent 82 from the valve actuating slide, which spring 92, being under tension, thereafter causes the valve actuating slide to move to its lowermost position to return the valve to exhaust position and cause Areengagement of the detent 79 with the slide. In this manner, with power fluid constantly supplied, the pistons operate, as hereinbefore described, to alternately move the valve 58 to position to direct the Huid pressure and to exhaust the same, resulting-in pumping action.

. By providing the ports-70 from the exhaust pipes 69 into the flow line 25 through block 24, the exhaust fluid isutilized to assist in elevating the Huid pumped from the well and to, in a measure, relieve the weight on piston 46. Furthermore by arranging the exhaust from passage 66 into the space between blocks 33 and 43 and locating the reliet1 valve 57 in this space any discharge by.

said valve also escapes through the exhaust pipes 69 and their connections.`

Various changes may be resorted to provided they fall within the spirit and scope of the invention.
